Enterprise-grade software infrastructure designed to automate and scale high-volume transactions via WhatsApp. The system acts as an autonomous intermediary managing real-time communication and complex business rules without human intervention. Technical Highlights:Architecture: Robust microservices backend built with Node.js and Express, orchestrated using Docker Compose. High-Volume Handling: Manages thousands of simultaneous conversations with millisecond response times and zero lag. Payment Validation: Innovative integration using MacroDroid to intercept Mercado Pago notifications and automated metadata analysis for anti-fraud verification. Intelligent Scoring: Automatic user categorization (New to VIP) based on transaction volume and history. Data Management: Real-time auditing via Google Sheets API with a roadmap for PostgreSQL/MongoDB migration. Security: Secured via JWT/API Keys and strict receipt timestamp validation.

A performance-optimized 2D arcade game and engine developed from scratch in C++, focusing on core software engineering principles, memory management, and real-time logic. This project demonstrates the ability to handle low-level programming and complex architectural patterns. Technical Highlights: Custom Engine: Developed a dedicated game loop and entity management system using Object-Oriented Programming (OOP) in C++. Physics & Collisions: Implemented custom 2D collision detection, gravity simulation, and kinematic character movement. Resource Management: Optimized sprite rendering and memory allocation to ensure smooth, high-frame-rate gameplay. AI & Logic: Programmed autonomous enemy behavior patterns and automated state-based level progression. Skills Demonstrated: Mastery of C++, algorithmic efficiency, and real-time system synchronization. Source code and GitHub repository access available upon private request.
